Fix/Solution for NoMethodError? (undefined method `controller_name’ for nil:NilClass)
This error appears when same action gets called twice. There might be chances to have controller with same name twice inside app as well as pluginsIn my case the error appeared while migrating from rails 2.1 to 2.3.Application was having application.rb and application_controller.rbFiles deleted:trunk/app/controllers/application.rbAnd that solved problem !
